Background. Several techniques have been introduced to treat acromioclavicular (AC) separation using the semitendinosus tendon as a graft for coracoclavicular (CC) ligament reconstruction. However, the tendon may have been used previously or the patient may not want it harvested. Hence, synthetic tendon transfers have become increasingly popular. Methods. Five patients with chronic AC separations were treated. A synthetic polyurethane urea tendon graft (Artelon Tissue Reinforcement [ATR]) was chosen for its ability to partially transform into connective tissue. The patient follow-up period lasted 45 to 60 months. Results. The mean preoperative Constant Score increased from 64.8 to 100 postoperatively. The mean preoperative Simple Shoulder Test increased from 7.2 to 12 postoperatively. The mean postoperative increase of the CC distance was 1.5 mm. The mean expansion of the clavicular drill hole from the original was 2.1 mm. According to the postoperative magnetic resonance imaging, the grafts had healed well and the cross-sections of the grafts were up to 10.5 mm between the coracoid and the clavicle. Discussion. The synthetic ATR tendon strip was a practical method for reconstructing a torn CC ligament complex. The ATR graft appears promising for future CC ligament reconstructions.

Background: There is no consensus on the ideal treatment for partial articular supraspinatus tendon avulsion (PASTA) lesions without tendon damage. Purpose: To introduce a novel “retensioning technique” for arthroscopic PASTA repair and to assess the clinical and radiologic outcomes of this technique. Study Design: Case series; Level of evidence, 4. Methods: A retrospective analysis was performed on 24 patients whose PASTA lesion was treated using the retensioning technique between January 2011 and December 2015. The mean ± SD patient age was 57.6 ± 7.0 years (range, 43-71 years), and the mean follow-up period was 57.6 ± 23.4 months (range, 24.0-93.7 months). Sutures were placed at the edge of the PASTA lesion, tensioned, and fixed to lateral-row anchors. After surgery, shoulder range of motion (ROM) and functional scores (visual analog scale [VAS] for pain, VAS for function, American Shoulder and Elbow Surgeons [ASES] score, Constant score, Simple Shoulder Test, and Korean Shoulder Score) were evaluated at regular outpatient visits; at 6 months postoperatively, repair integrity was evaluated using magnetic resonance imaging (MRI). Results: At 12 months postoperatively, all ROM variables were improved compared with preoperative values, and shoulder abduction was improved significantly (136.00° vs 107.08°; P = .009). At final follow-up (>24 months), the VAS pain, VAS function, and ASES scores improved, from 6.39, 4.26, and 40.09 to 1.00, 8.26, and 85.96, respectively (all P < .001). At 6 months postoperatively, 21 of the 24 patients (87.5%) underwent follow-up MRI; the postoperative repair integrity was Sugaya type 1 or 2 for all of these patients, and 13 patients showed complete improvement of the lesion compared with preoperatively. Conclusion: The retensioning technique showed improved ROM and pain and functional scores as well as good tendon healing on MRI scans at 6-month follow-up in the majority of patients. Thus, the retensioning technique appears to be reliable procedure for the PASTA lesion.

Background: This study aimed to evaluate the response rate to arthroscopic release treatment in adhesive capsulitis of the shoulder (ACS) for patients with refractory to conservative treatment. Methods: In this retrospective study, 51 patients (age mean, 49.1±5.6 years) with unilateral adherent capsule underwent arthroscopic releasing surgery for the shoulder capsule. Etiologies of the ACS in 30 patients were idiopathic: 10 patients were affected after surgery and 11 patients following trauma. The patients were evaluated in terms of shoulder function, satisfaction rate, pain intensity, and joint range of motion (ROM) based on a Constant score, a simple shoulder test, the visual analog scale, and four movements, respectively.Results: The mean Constant score before surgery was 48.2±3.5 and reached 74.4±6 and 77.0±6.3 at 6 months and the final follow-up, respectively (p<0.001). The mean scores of pain intensity, a simple shoulder test, and ROM showed significant improvement at all follow-ups (p<0.001). Sex, age, and diabetes did not have any significant effect on patient recovery. However, patients who experienced ACS after surgery had poorer results than others at all follow-up points. Conclusions: Arthroscopic releasing surgery of the shoulder in patients with ACS refractory to conservative treatment produces rare complications and an effective injury response. It seems that patients suffering ACS following surgery have a weaker response to the treatment.

Background: Sternal fractures are rare, and they can be treated nonoperatively. Vertical sternal fractures have rarely been reported. Purpose: To describe the management and surgical treatment of a series of elite-level athletes who presented with symptomatic nonunions of a vertical sternal fracture. Study Design: Case series; Level of evidence, 4. Methods: Patients with an established symptomatic nonunion of a vertical sternal fracture, as diagnosed by computed tomography (CT) or magnetic resonance imaging (MRI), underwent open reduction and internal fixation using autologous bone graft and cannulated lag screws. The patients were assessed preoperatively and at the final follow-up using the Rockwood sternoclavicular joint (SCJ) score; Constant score; and shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores. Bony union was confirmed on postoperative CT scan. Results: Five patients (4 men and 1 woman) were included; all were national- or international-level athletes (rugby, judo, show-jumping, and MotoGP). The mean age at surgery was 23.4 years (range, 19-27 years), the mean time from injury to referral was 13.6 months (range, 10-17 months), and the mean time from injury to surgery was 15.8 months (range, 11-20 months). The mean follow-up was 99.4 months (range, 25-168 months). There was a significant improvement after surgery in the mean Rockwood SCJ score (from 12.6 to 14.8 [ P < .05]), Constant score (from 84 to 96.4 [ P < .05]; 80% met the minimal clinically important difference [MCID] of 10.4 points), and QuickDASH (from 6.8 to 0.98 [ P < .05]; 0% met the MCID of 15.9 points). Four of the patients were able to return to sport at their preinjury level, and 1 patient retired for nonmedical reasons. All of the fractures had united on the postoperative CT scan. There were no postoperative complications. Conclusion: Vertical fractures of the sternum are very rare and tend to behave clinically like an avulsion fracture injury to the capsuloligamentous structure of the inferior SCJ. The requirement of advanced imaging to diagnose this injury means that the actual incidence and natural history are not known. For high-demand athletes, early identification, surgical reduction, and fixation are likely to achieve the best outcome.

The aim of the study was to evaluate the results of the medial patellofemoral ligament reconstruction with a medial strip of patellar tendon autograft after a minimum 2-year followup. Ten patients (10 knees) were operated on by one surgeon, according to the modified technique, described by Camanho, without any bone plug at free graft end. The mean age of the patients was 27.2 years (ranging from 18 to 42 years). The mean follow-up period was 3 years and 7 months. All patients were reviewed prospectively. At the last follow-up visit, all the patients demonstrated a significant improvement in terms of patellofemoral joint stability, all aspects of the KOOS questionnaire, and Kujala et al.’s score (59.7 points preoperatively and 84.4 points at the last followup). No patient revealed recurrent dislocation. The SF-36 score revealed a significant improvement in bodily pain, general health, physical role functioning, social role functioning, and physical functioning domains. The described MPFL reconstruction with the use of the medial 1/3rd of patella tendon is an effective procedure that gives satisfactorily patellofemoral joint functions, improves the quality of life, and provides much pain relief. It is relatively simple, surgically not extensive, and economically cost-effective procedure.

Aims The reasons for failure of a hemirthroplasty (HA) when used to treat a proximal humeral fracture include displaced or necrotic tuberosities, insufficient metaphyseal bone-stock, and rotator cuff tears. Reverse total shoulder arthroplasty (rTSA) is often the only remaining form of treatment in these patients. The aim of this study was to evaluate the clinical outcome after conversions from a failed HA to rTSA. Material and Methods A total of 35 patients, in whom a HA, as treatment for a fracture of the proximal humerus, had failed, underwent conversion to a rTSA. A total of 28 were available for follow-up at a mean of 61 months (37 to 91), having been initially reviewed at a mean of 20 months (12 to 36) postoperatively. Having a convertible design, the humeral stem could be preserved in nine patients. The stem was removed in the other 19 patients and a conventional rTSA was implanted. At final follow-up, patients were assessed using the American Shoulder and Elbow Surgeons (ASES) score, the Constant Score, and plain radiographs. Results At final follow-up, the mean ASES was 59 (25 to 97) and the mean adjusted Constant Score was 63% (23% to 109%). Both improved significantly (p < 0.001). The mean forward flexion was 104° (50° to 155°) and mean abduction was 98° (60° to 140°). Nine patients (32%) had a complication; two had an infection and instability, respectively; three had a scapular fracture; and one patient each had delayed wound healing and symptomatic loosening. If implants could be converted to a rTSA without removal of the stem, the operating time was shorter (82 minutes versus 102 minutes; p = 0.018). Conclusion After failure of a HA in the treatment of a proximal humeral fracture, conversion to a rTSA may achieve pain relief and improved shoulder function. The complication rate is considerable.

Abstract Background The medial patellofemoral ligament (MPFL) is always damaged after patellar dislocation. In selected patients, MPFL reconstruction is necessary to restore a correct patellar tracking. Despite the large number of different techniques reported to reconstruct the MPFL, there is no consensus concerning the optimal procedure, and debates is still ongoing. The present study analysed the results after isolated MPFL reconstruction in patients with patellofemoral instability. Furthermore, a subgroup analysis of patients presenting pathoanatomical risk factors was made. Methods In November 2020, the main electronic databases were accessed. All articles reporting the results of primary isolated MPFL reconstruction for recurrent patellofemoral instability were considered for inclusion. Only articles reporting a minimum 12-month follow-up were eligible. Results Data from a total of 1777 knees were collected. The mean age of the patients involved was 22.8 ± 3.4 years. The mean follow-up was 40.7 ± 25.8 months. Overall, the range of motion (+ 27.74; P < 0.0001) and all the other scores of interests improved at last follow-up: Kujala (+ 12.76; P = 0.0003), Lysholm (+ 15.69; P < 0.0001), Tegner score (+ 2.86; P = 0.006). Seventy-three of 1780 patients (4.1%) showed a positive apprehension test. Thirty of 1765 patients (1.7%) experienced re-dislocations, while 56 of 1778 patients (3.2%) showed persisting joint instability. Twenty-five of 1786 patients (1.4%) underwent revision surgeries. Conclusion Isolated MPFL reconstruction for recurrent patellofemoral instability provides reliable surgical outcomes. Patients with pathoanatomical predisposing factors reported worse surgical outcomes.

Clinical studies on primary osteoarthritis have shown better results of total shoulder arthroplasty (TSA) compared to hemiarthroplasty (HA) regarding the function, revision rate and postoperative pain relief. However, a clear recommendation for implantation of TSA or HA, depending on the glenoid type of erosion, does not exist. The aim of the study was to compare the results of TSA and HA with respect to the preoperative glenoid type. In this study, 41 patients were examined retrospectively; among them, 25 patients were treated with stemmed anatomic TSA and 16 with stemmed anatomic HA. The degree of osteoarthritis was determined according to Samilson and the glenoid erosion was classified according to Walch. The clinical outcome of the patients was determined by using the Constant Score (CS) and the Simple Shoulder Test at final follow-up. Patients after TSA demonstrated a significantly improved internal rotation compared to HA patients. Patients with preoperative B1 glenoid showed better pain relief after TSA compared to HA. For patients with preoperative type A2 glenoid a significantly higher CS was found after TSA compared to HA. We were able to show good short-term results after TSA and HA. Our findings suggest a better internal rotation for TSA compared to HA, superior clinical outcome for patients with preoperative A2 glenoid and lower pain level for patients with a preoperative B1 glenoid. However, these results need to be confirmed by further studies.

Abstract Objective The open Bristow procedure is a long established and effective method for treating anterior shoulder instability. Following the trends of minimally-invasive surgeries, these procedures were performed arthroscopically, and their outcomes were evaluated. Methods A total of 43 shoulders of patients submitted to Bristow procedures by arthroscopy, using a graft positioned horizontally and a screw, with at least two years of postoperative follow-up, were evaluated regarding quality of life, de novo dislocation index, and loss of lateral rotation. Results The mean follow-up time was of 76 months (range: 129 to 24 months). The University of California at Los Angeles (UCLA) score varied from 25.56 ± 0.50 (standard deviation [SD] = 3.25) to 33.23 ± 0.44 (SD = 2.91) (p < 0.0001). Two or more years after surgery, the mean Rowe score was of 94.25 ± 1.52 (SD = 1.34), whereas the good results standard is 75 (p < 0.0001). The mean value for the simple shoulder test was of 11.35 ± 0.21 (SD = 1.34), while the mean value of the lateral rotation loss was of 10.37° ± 1.36° (SD = 8.58°). There were no de novo dislocations.In total, there were 12 complications, 8 of which had no clinical repercussions. The clinically-significant complications included an infection six months after surgery with a potential hematogenous origin, a coracoid fracture that required an intraoperatively procedure change, and two patients with previous impingement who required synthesis material removal more than six months after surgery. Conclusion Although the arthroscopic Bristow procedure was effective in treating anterior shoulder instability, it is not a complication-free surgery.

Background: Acromioclavicular (AC) joint separation is a common injury. The anatomic coracoclavicular ligament reconstruction (ACCR) technique is a viable treatment option, designed to restore the native joint anatomy. Purpose: To evaluate the clinical and radiographic outcomes of patients undergoing ACCR for the treatment of type III and V AC joint injuries with a minimum 2-year follow-up. Study Design: Case series; Level of evidence, 4. Methods: A retrospective chart review was performed on prospectively collected data. Patients who underwent ACCR for type III or V AC joint injuries between January 2003 and December 2015 were analyzed. Clinical outcome measures included the American Shoulder and Elbow Surgeons (ASES) score, Rowe score, Simple Shoulder Test (SST), and Constant-Murley (CM) score. To determine the clinical relevance of the ASES score, the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptomatic state (PASS) were used. The pre- and postoperative coracoclavicular distance (CCD) and side-to-side difference in the CCD were measured for radiographic analysis. Results: A total of 43 patients (22 acute, 21 chronic) were included in the study. The mean patient age was 43.4 ± 11.4 years, with a mean follow-up of 3.4 years (range, 2.0-7.5 years). With regard to the ASES score, 92% of patients achieved the MCID, 81% achieved the SCB, and 49% reached or exceeded the PASS. There was no significant difference when stratifying by type (III vs V) or chronicity (acute vs chronic) of injury (both P > .05). The Rowe score improved from 66.6 ± 15.9 preoperatively to 88.6 ± 12.3 postoperatively, the CM score from 61.6 ± 18.8 to 87.4 ± 15.1, and the SST score from 6.2 ± 3.6 to 9.4 ± 3.7 (all P < .001). The postoperative side-to-side difference in the CCD was 3.1 ± 2.7 mm, with type III injuries (2.4 ± 1.9 mm) showing significantly lower measurements compared with type V (4.2 ± 3.4 mm) ( P = .02). No significant trend was found between joint reduction and the improvement in clinical outcomes ( P > .05). Conclusion: Patients undergoing ACCR for acute and chronic type III and V AC joint injuries maintained significant improvement in clinical and radiographic outcomes at a minimum 2-year follow-up. Additionally, 81% of patients reached the SCB after surgical reconstruction.
